Tools and Exploits

  • chrome-bandit is a proof of concept to show how your saved passwords on Google Chrome and other Chromium-based browsers can easily be stolen by any malicious program on macOS.
  • TREVORproxy is a SOCKS proxy written in Python that randomizes your source IP address. Round-robin your evil packets through SSH tunnels or give them billions of unique source addresses!
  • chronorace is a tool to accurately perform timed race conditions to circumvent application business logic. Well timed race conditions can allow for uncovering all kinds of interesting edge cases. Here is a good example.
  • RefleXXion is a utility designed to aid in bypassing user-mode hooks utilised by AV/EPP/EDR etc. In order to bypass the user-mode hooks, it first collects the syscall numbers of the NtOpenFile, NtCreateSection, NtOpenSection and NtMapViewOfSection found in the LdrpThunkSignature array.
  • Sliver v1.5.0. This release has a lot of cool changes. My favorite is BOF support!
  • FunctionStomping is a new shellcode injection technique. Given as C++ header or standalone Rust program. Currently undetected by hollows-hunter.
  • SharpGhosting is Process Ghosting (x64 only) in C#.
  • CVE-2021-45467: CWP CentOS Web Panel – preauth RCE. File inclusion + directory traversal = RCE.
